Combination lock-hinge



NlTED STATES EMIL LUNDGREN, OF BUTLER, PENNSYLVANIA.

COMBINATION LOCK-HINGE.

SPECIFICATION forming part of Letters Patent No. 530,436, dated December4, 1894;.

Application filed August 14, 1894- Serial No.520,323. (N model.)

I detachably securing the pintle of a door, window, or other hinge inengagement with the eyes of the leaves, to prevent accidentaldisplacement and at the same time permit the removal thereofwhen'necessary to detach the door or window.

Further" objects and advantages of the invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings :Figure 1 is a perspective view of a hinge embodying myinvention.

. Fig.2 is a vertical section of the same through the axis of thepintle-rod. Fig. 3 is a detail view of the pintle-rod, detached. Fig. 4is a detail view of the eyes and tumblers forming the hinge, detached.Fig. 5 is a similar view,

showing the parts reversed.

Similar numerals of reference indicate corresponding parts in allthefigures of the drawings.

1 and 2 designate, respectively, the opposite leaves of the hinge, ofwhich the leaves 2 are provided with twin spaced eyes 3 between whichthe single eyes 4 of the leaves 2 are fitted. Through these registeringeyes extends the removable pintle-rod 5, providedat one end with a knobor handle 6, the shoulder 7 at the inner end of which abuts against theadjacent outer side of the contiguous eye. The pintle-rod is providedwith spaced studs or projections 8 and the eyes adjacent to the.

knob or handle 6 are provided in their bores with corresponding notches9 to enable the rod to be inserted with facility, by allowing thesestuds or projections to pass. The opposite end of the pintle-rod, whichis arranged in the other set of registering eyes, is reduced or tapered,and fits in a cap 10 provided with a socket for the reception of theextremity of the pin'tle-rod and having a reduced portion 11 whichextends into the adjacent eye of a hinge-leaf. This reduced portion 11is provided in its outer surface with an annular groove 12 adapted toreceive a lug 13 within said adjacent eye of the hinge-leaf, this groovehavinga communicating or outlet slot 14: to

facilitate the insertion of the reduced portion of the cap in the eye.After the insertion of the reduced portion the cap is partially rotated,to move the outlet slot out of registrathe intermediate or spacingshells have bores which are sufficiently large to allow the studs orprojections to pass freely. The adjacent tumblers and spacing shells areprovided at their contiguous ends, respectively, with annularprojections or extensions 18 and receiving cavities or sockets 19, tomaintain the parts in alignment, and the terminal spacing shells, whichare contiguous to the inner eyes of the hinge-leaves are provided attheir outer sides with similar projections or extensions 20 to fitincavities or sockets 21 in the inner sides of said eyes.

With the parts in the positions shown in Figs. 1 and 2 or assembled, itis necessary, in order to withdraw the pintle-rod, to turn the severaltumblers until their longitudinal grooves 17, (which correspond with thehereinbefore described grooves or notches 9 in the hinge-eyes adjacentto the knob or handle of the pintle-rod,) agree or align with the studsor projections on the pintle-rod. This alignment is facilitated by themarks or indices 23 with which the tumblers are provided, the properalignment being attained when said marks or indices align with a similarmark or indicator 24 on the hinge-eye adjacent to the knob or handle ofthe pintle-rod. It will IOC be understood that the assembling of theparts of the hinge is accomplished by the reversal of the abovedescribed operation, and that after the insertion of the pintle-rod thetumblers should be turned to move their grooves or notches 7 out ofalignment with the studs or projections of the pintle-rod. The cap ispreferably shaped, as shown, to correspond with the knob or handle, tosecure symmetry of the hinge.

Various changes in the form, proportion, and minor details ofconstruction may be resorted to Without departing from the spirit orsacrificing any of the advantages of the invention.

Having thus described my invention, I claim 1. The combination withhinge-leaves having interlocking eyes provided with registering bores,of a pintle-rod engaging said eyes, and a series of tumblers concentricwith the pintle-rod, said tumblers and pintle-rod be ing provided withintermeshing projections and notches, substantially as specified.

2. The combination with hinge-leaves having registering eyes, of apintle-rod engaging said eyes and provided with studs or projections,spaced tumblers concentric with the pintle rod, spacing shellsinterposed between the tumblers, said tumblers being provided withgrooved bores to receive the studs or projections of the pintle-rod,substantially as specified.

3. The combination with hinge-leaves having registering eyes, of apintle-rod engaging said eyes and provided with studs or projections, aknob or handle attached to one end of the pintle-rod, a series oftumblers rotatably mounted concentric with the pintle-rod and providedwith grooves to allow the passage of the studs or projections on thepintlerod, and a cap removably fitted upon a hingeeye adjacent to theend of the pintle-rod opposite to the said knob or handle, substantiallyas specified.

4. The combination with hinge-leaves having registering eyes, of apintle-rod provided at one end with a knob or handle and at intervalswith studs or projections, a cap attached to a hinge-eye at the oppositeend of the pintle rod and having 'a reduced portion fitting in the boreof said eye and provided with a groove which is engaged by a lug in theeye, spaced lugs concentric with the pintlerod and provided withlongitudinal slots to receive the studs or projections thereon, andinterposed spacing shells having enlarged bores, said tumblers andinterposed shells being provided at their contiguous ends, respectively,with engaging extensions and cavities, and the terminal shells beingprovided with corresponding extensions which engage cavities in theinner sides of contiguous eyes, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

EMIL LUNDGREN.
